Backups: The One Thing Everyone Skips Until It's Too Late

Of all the tech advice we give, this is the one people most wish they'd taken sooner: back up your data. Drives fail without warning, ransomware can lock up everything in seconds, laptops get lost, stolen, or dropped, and a single wrong click can delete years of photos. When it happens, recovery is often impossible or expensive — but a good backup turns a disaster into a minor inconvenience.

The rule that actually works: 3-2-1

The standard worth remembering is the 3-2-1 rule: keep 3 copies of anything important, on 2 different types of media, with 1 of them stored offsite (or in the cloud). That way no single failure — a dead drive, a house fire, a theft, a ransomware infection — can take out everything at once.

Important: syncing is not backing up

A lot of people assume Google Drive, OneDrive, iCloud, or Dropbox are their backup. They're not — they're sync. If a file gets deleted, corrupted, or encrypted by ransomware on your computer, that change syncs up to the cloud too, and the good version is gone. Sync is convenient, but real backup keeps separate, versioned copies you can roll back to.

The main options and providers

What we recommend, in order. At a bare minimum, turn on the backup already built into your operating system — on Windows that's File History / Windows Backup, on a Mac it's Time Machine. It's free, it's included, and it's far better than nothing. But treat it as the floor: Windows' built-in option leans on OneDrive folder sync with limited free space, so it isn't a true, complete offsite backup.

For real offsite protection we recommend Backblaze — it quietly backs your whole computer up to the cloud for a low flat price (iDrive, Carbonite, and Acronis are fine alternatives). And if you'd rather not pay a subscription or hand your data to a third party, we've got you covered with our own solution (below) that runs on storage you own.

Local backup: an external hard drive paired with the tools already built into your computer — Time Machine on a Mac, File History on Windows — gives you a fast, free local copy. For a home or small business with several computers, a NAS (network drive) is a tidy central option.

The best setup is usually both: a local backup for quick restores and a cloud backup for the offsite copy — which is exactly the 3-2-1 rule in practice.

Our custom option: your own storage, protected against bitrot

If you'd rather not hand your data to a subscription — or you simply have a lot of it — we also build a custom backup solution that runs on your own storage. We set you up across multiple drives with redundancy, so your backup isn't trusting a single disk. That also protects against "bitrot": the silent data corruption that can quietly creep into files sitting on one drive over the years, where a photo or document slowly goes bad without anyone noticing.

It's the same principle Backblaze uses to keep data safe — spread it across drives so one failing or corrupting disk can't take your data with it — but run on hardware you own. No monthly storage fee, full control of where your data lives, and protection that doesn't hinge on one drive staying healthy. We size it to how much you need to protect and set it to run automatically.

Make it automatic — and test it

The backup that actually saves you is the one that runs by itself, because manual backups get forgotten. Set it to run automatically, and then — this is the step everyone skips — occasionally check that you can actually restore a file from it. A backup you've never tested isn't a backup yet; it's a hope.

We set up backups for homes and small businesses all the time: picking the right mix of local and cloud, automating it so you never think about it, and verifying that it restores. It's the cheapest insurance in technology — and we'd much rather set yours up than try to recover data that was never backed up.
